My circuit takes some microswitches as inputs and based on them sends some data on the serial port. After few hours it hangs randomly.
I think it is because of the inputs since I connected the switches directly to the AVR port.
Should I use opto coupler for example to solve this issue? Could anyone please give a solution for this?
